Our Process for Comparison:

The EnergyPlus model results for different versions of ASHRAE codes were obtained by running the PNNL models of different building types. The same inputs were used to generate the cove.tool results which were calibrated later to match the EnergyPlus Results. The results that follow indicate that cove.tool is on average within 5% of all EnergyPlus simulations. The weather files used were the representative city for each zone.

BUILDING TYPES:

Small Office

  1. All cove.tool models are within 8.5% when compared to respective Energy Plus models.

  2. The Fan loads for 2010 and 2013 ASHRAE models are approx. 50% less and 50% more for respective cove.tool models.
